## Practice the backup before you need the backup

A backup on a map is not a backup until the handoff has survived a realistic attempt.

### Use when

- Your expertise map names a backup, but nobody knows whether that person can actually carry a recurring critical task when the primary is unavailable.

### Avoid when

- Do not rehearse on live high-risk systems without safeguards. Licensed, regulated or safety-critical work may require formal authorization and supervised training. Cross-training depth produced inconsistent findings in the experimental literature, and much of the evidence is simulation-based; demonstrated backup readiness does not make people interchangeable experts.

### Explanation

Choose one recurring, consequential workflow with a single point of failure. Let the backup perform a realistic case while the primary observes only at agreed stop points. Capture missing decision cues, access, artifacts and escalation conditions, fix those gaps, then repeat with the primary unavailable. Cross-training studies support shared interaction models and coordination, but much of the evidence comes from simulations and does not imply that every role should be duplicated.

### Steps

1. Pick one task where primary-person absence would materially delay or endanger the work. Define success, stop conditions and the escalation route.
2. Give the backup the current artifact and a minimal walkthrough, then let them execute a realistic case rather than merely watch the primary.
3. Record each failure as a concrete gap: missing context, permission, tool, decision cue, artifact or escalation rule. Repair the smallest useful gap.
4. Retest after the repair or a meaningful system change with the primary unavailable. Keep the formal owner and escalation path explicit.

### Example

An integration team lists a second engineer as backup for payment-retry incidents. During rehearsal, the backup discovers a hidden dashboard permission and an undocumented rollback threshold. The team fixes the access and records the threshold; on the next drill, the backup can complete the case without the primary.

### Check

With the primary unavailable, the backup can either complete the defined case safely or stop at the right boundary and escalate using current artifacts and permissions.

### Limits

- Do not rehearse on live high-risk systems without safeguards. Licensed, regulated or safety-critical work may require formal authorization and supervised training. Cross-training depth produced inconsistent findings in the experimental literature, and much of the evidence is simulation-based; demonstrated backup readiness does not make people interchangeable experts.

### Evidence and sources

- supports: Across two computer-simulation experiments with 45 and 49 teams, cross-training enhanced shared team-interaction mental models; coordination mediated the relationship between those shared models and team performance. — RS-85FBF9764660FB3E9E89. The tasks were simulations, and the authors reported inconsistent findings about the depth of cross-training needed to improve shared mental models. (Abstract)
- limits: A 2007 meta-analysis found a small-to-moderate tendency for team training to improve team performance, while its analyses suggested that coordination and adaptation training contributed more strongly than cross-training alone. — RS-F8EB6521EF7C07182E49. The evidence base was small; the main analysis treated multiple tests from some studies as independent, although a supplemental seven-study analysis showed the same broad pattern. This does not identify one universally optimal training mix. (Abstract and supplemental independence analysis)
- contextualizes: A 2024 scoping review of 213 cross-disciplinary sources on team adaptation recommends realistic training with actual teams and highlights shared mental models, contingency planning, roles and responsibilities as relevant learning objectives. — RS-4B65D6D807889A08CCF5. The review synthesizes heterogeneous experimental, observational and conceptual work. Its training recommendations are not a causal test of the rehearsal protocol in this card.
